When it comes to building your retirement nest egg, you’ve probably heard a lot about different investment strategies. A common starting point for many SMSF trustees is to look at defensive assets like cash and bonds. Many people see these assets as safe and sensible, but it pays to understand what they are, what they do, and, more importantly, what else might be missing from your investment portfolio.


Understanding Cash Investments

Let’s start with cash investments. In the world of SMSFs, this means choosing to hold a portion of your fund’s money in secure and highly liquid assets. These include high-interest savings accounts or term deposits held in the name of your SMSF. The appeal of this investment portfolio choice is pretty simple: it’s safe. It’s the most liquid asset you can have in your SMSF because it’s readily available whenever you need it. This makes it a great buffer for paying expenses or waiting for the right moment to make a bigger move.


The biggest reward with cash is capital preservation—your money is secure, and you know exactly how much you have. However, the downside is that the returns are typically low. Another risk is that its returns often don’t keep up with inflation. Your purchasing power could go down over time, which isn’t ideal for a long-term retirement investing strategy.


Exploring Different Types of Bonds

Next up are bonds. When you buy a bond, you’re essentially lending money to a government or a corporation. In return, they promise to pay you back the principal amount on a specified date and provide regular interest payments along the way.

There are many different types of bonds. For example, government bonds are generally considered safe because they’re backed by a government. Corporate bonds, on the other hand, are issued by companies and tend to offer higher returns because they carry higher risk.


The rewards of having bonds in your SMSF investment portfolio include a more stable income stream compared to stocks and a bit more growth potential than cash. However, they’re not without bond investment risks. The main one is interest rate risk: if market interest rates rise, the value of your existing bonds can fall. There’s also a risk that the bond issuer could default and not be able to pay you back.


The Big Picture: Cash vs Bonds

So, which ones should you choose for your SMSF investment portfolio? Cash or bonds? Here’s a quick explanation of their differences:


- Cash

is for stability, liquidity, and a low-risk foundation.

- Bonds

Are for slightly better returns and a predictable income stream. You don’t have to pick one over the other. You can have both in your portfolio. Together, they can create a stable, defensive portion of your SMSF. But here’s the crucial question: Is “stable and defensive” enough to reach your retirement goals? A resilient investment portfolio needs balance. It requires assets that offer both stability and the potential for substantial capital growth.

The Importance of a Diversified Investment Strategy

Before we go any further, it’s important to remember that every SMSF is required to have a documented investment strategy. This strategy isn’t just a formality—it’s a vital roadmap that outlines your investment goals, risk tolerance, and specific plans for attaining them. The ATO requires that your strategy considers diversification. Simply put, this means not putting all your eggs in one basket.


Having a balanced mix of defensive assets (like cash and bonds) and growth assets (like property or shares) is key. This is the foundation of building a robust fund that can withstand market fluctuations while still aiming for strong, long-term growth.


The Missing Piece: Your Property Portfolio

This is where a property portfolio comes into the picture. Investing in property through your SMSF offers two powerful benefits:


1. Capital Growth:

Over the long term, well-chosen properties tend to increase in value.


2. Rental Income:

The rent you collect from tenants provides a regular income stream for your fund.

This combination of capital growth and rental income can transform your SMSF, helping it grow much faster than it could with just cash and bonds. The best part? You don’t need to have all the cash upfront to make it happen. Just like an individual, your SMSF can take out a loan to buy an investment property.


Grasping the Concept of Leverage for SMSF Investments

Leverage is a financial term that simply means using borrowed money to increase your potential returns. When you use an SMSF loan to buy a property, you’re leveraging the fund’s capital. This is a huge boost for two key reasons:


- Accelerated Growth:

Instead of waiting years to save enough cash to buy a property outright, a loan allows you to start benefiting from capital growth and rental income much sooner.

- Maximising Your Investment:

Through LRBA, you might use 20% of your fund’s capital as a deposit and borrow the remaining 80%. This means the fund is now invested in a much larger asset, and you can potentially earn returns on the entire property’s value, not just your initial deposit.
